You might also experiment with viney legumes that can compete with it such as
vetches or annual field peas, just to weaken the stand. Obviously, you will
have to fence the animals out of the area temporarily while doing this. If
the ground ivy is heavy, you should be able to sow seed directly into it and
mow the ivy to cover the seed. Another important cover crop to try is
buckwheat, sown the same way. Buckwheat is suitable as a component of
grazing.
Plowing is a waste of time and energy unless you plant a crop such as corn or
potatoes that can smother the ground ivy. Youd have to do that several years
running. Surely, you have a problem that is just going to a measure of added
work for as long as you run sheep.
